Hi guys, i have sound card u46mk2. I have just bought brand new timecode vinyl and downloaded demo version of Cross. Everything is ok, but one difficulty. The sound is really wierd, when i go to the preferences->vinyl/cd in the quality of signal i see like 32-55% sometimes it goes up to 90% and sound is cool, but most of the time it's pretty low. So what could it be? Why quality of sound is too low when input signal comes from brend new timecode vinyl?
Thanx/

Are these MixVibes timecode ?
You should set the U46 to Line and Cross to phono.

Hi, yea the vinyl is mixvibes. I have set the Cross to phono and u46 to phono too. If u46 is set to line there is no signal at all. To day it shows like 80-90%. So what else makes impact on signal quality, except timecode record?

This is not the correct settings because actually you're applying a riaa filter to a signal that have almost be riaa filtered by the preamp of the soundcard.

Send me a screenshot of the waveform.

There is no difference when i turn phono/line in Cross. But if it's set for 48000Hz quality goes to 97%.
But still, why there is no sound when card is turned to line?

What are your turntables ? does they have key lock/master tempo ?
the output is phono or line ?
Your Windows is a x86 or x64 version ?

As far as I can remember the mk5 have no 0% pitch marker but if I my memories are right there is a button with which you can set the pitch to 0%. This is important for calibration. Have you set it to 0%?

Sure, I have set pitch for 0% before calibration.
I got one more question, how can I check the card for issues, i mean to see if it works properly. It has been used before me. So maybe something wrong with it.

Go to your system preferences into the audio & sound options and set your u46 as a standard interface. Open your media player (vlc, winamp, iTunes,...) and check if you can configure the output so that the sound is played through the u46. If you can not configure it in the program the media player uses the windows default soundcard that you set to u46.

It would be more interesting to test the inputs because this is where your timecode gets through. Use any recording program i.e. Audacity which is a free tool. There you can configure in the sound options which input it should record. Please choose the u46 input and record sound you send into the input. If this works the interface seems to be okay.
